Description

Technical Field

[0001] The invention relates to the technical field of rock wool strip production, and in particular to a cross-cutting device and a cross-cutting method for producing rock wool strips. Background Art

[0002] Since there are many types of fireproof isolation belt strips and a wide range of processing widths, it is necessary to frequently replace and adjust the number and spacing of cutters on the main shaft. However, both ends of the main shaft of conventional rock wool equipment are installed on the shaft seat. Fixing the main shaft in this way is not conducive to rapid disassembly and assembly of equipment, and replacing cutters and repairing and maintaining are time-consuming and labor-intensive, resulting in difficulty in disassembly and assembly of equipment. The product specification width is 600mm, which cannot directly produce the fireproof isolation belt strips with a thickness of generally 50-150mm required in construction projects. In addition, during the cutting of rock wool strips, the rock wool strips are prone to blockage and deviation. The Chinese patent number is: CN116619581B discloses a "Rock Wool Board Cutting Device". In this patent, the circular saw blade of the cutting mechanism is driven into the cutting position by a telescopic rod, so that the appropriate cutting mechanism can be selected for cutting according to the width of the rock wool board, while the circular saw blades of other cutting mechanisms will not rotate, thereby reducing the energy consumption of the equipment and increasing the service life of the equipment. Multiple cutting mechanisms are connected to a synchronous equidistant driving mechanism. When the synchronous equidistant driving mechanism adjusts the distance between the circular saw blades of the cutting mechanism, the distance between multiple adjacent circular saw blades can be changed synchronously, and the distance between adjacent circular saw blades can be kept the same.

[0003] Due to structural design defects, the existing cross-cutting equipment and cross-cutting methods used for rock wool strip production have the problem that the rock wool blocks are easily deviated during the cutting process of rock wool strip production, affecting the cutting accuracy, and the rock wool block cross-section is squeezed during the cutting process due to extrusion cutting, which easily leads to defects such as warping and deformation at the cut section.

At this time, the corners of the rock wool block are in close contact with the clamping assembly, and the external force pushes the rock wool strip to fit the clamping assembly completely. Step 2: Synchronously drive. When the friction belt drives the rock wool block and the bending rod to approach the reciprocating cutting mechanism, the slider slides on the inner side of the guide rail, and the surface of the guide pulley rolls on the surface of the guide rail near the opening.

Complete the cutting. The fixed table supports and limits the rollers and the shell. The surfaces of multiple rollers are in close contact with the surface of the sawing strip near the end face. The rectangular frame drives the sawing strip to move up and down quickly. The saw teeth cut the rock wool block. The limitation of the second L-shaped plate makes it difficult for the rock wool block to deflect. Moreover, after the cutting of the rock wool block is completed, the sawing strip penetrates into the interior of the C-shaped frame, and the rock wool block will not disperse during the entire cutting process.

[0017] The present invention provides a cross-cutting device and a cross-cutting method for producing rock wool strips, which have the following beneficial effects: 1.

[0018] 2. The cross-cutting equipment and method for producing rock wool strips, the sliding of the slider allows the impurities deposited on the inner side of the guide rail to fall through the opening, thereby avoiding blockage of the slider movement, and the rock wool block and the bending rod are pushed. The softer sides, top and bottom of the rock wool block are not subjected to extrusion pressure, and the harder corner positions are clamped and limited. Under the condition that the rock wool block will not be deflected, the rock wool block will not be subjected to extrusion pressure during cutting, so that after the clamping force is removed, the cut surface of the rock wool block is smoother.

[0019] 3. The cross-cutting equipment and method for producing rock wool strips effectively restrict the corner positions of the rock wool blocks when they are cut by the sawing assembly to prevent the rock wool blocks from being deflected by the cutting force.

[0020] 4. The cross-cutting equipment and method for producing rock wool strips, the eccentric setting of the eccentric wheel enables the rectangular frame to reciprocate up and down on the inner side of the shell, so that the sawing strip can quickly cut the rock wool block. During this process, the second motor is always rotating in the same direction. The eccentric wheel is used to replace the hydraulic reciprocating movement, which will not cause emergency stop impact or hydraulic reverse impact, so that the rectangular frame moves up and down more smoothly and the structure is not easily damaged. The sliding guide of the slide rod makes the rectangular frame more stable and reliable when it moves up and down quickly.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] First embodiment: Figure 1-Figure 4As shown, the present invention provides a technical solution: a cross-cutting device and a cross-cutting method for producing rock wool strips, comprising a support table 1, a first motor 2 is fixedly connected to the upper position of the support table 1 surface, a rotating roller 3 is fixedly connected to the output end of the first motor 2, a spacer ring 4 is fixedly connected to the surface of the rotating roller 3, and a friction belt 5 is sleeved on the surface of the rotating roller 3, and further comprising: A positioning and pushing block mechanism 6, the bottom of which is fixedly installed above the surface of the support platform 1, and the number of friction belts 5 is several. The surface of the positioning and pushing block mechanism 6 is fixedly connected to the top of the friction belt 5 near the position of the first motor 2. The positioning and pushing block mechanism 6 is used for clamping the corner position of the rock wool block and limiting the position of the rock wool block during cutting; A reciprocating cutting mechanism 7, the bottom of which is fixedly mounted on the surface of the support platform 1 near the middle, and the reciprocating cutting mechanism 7 is used to saw the rock wool block into a plurality of rock wool strips; The positioning and pushing block mechanism 6 includes a guide rail 61, the bottom of which is fixedly installed above the surface of the support platform 1, the inner side of the guide rail 61 is slidably connected with a driving component 62, the top of the driving component 62 is fixedly connected with an electric cylinder 63, the rotating shaft at the output end of the electric cylinder 63 is fixedly connected with a telescopic rod 64, and the output end of the telescopic rod 64 is fixedly connected with a clamping component 65; One end of the driving component 62 away from the guide rail 61 is fixedly installed on the top of the friction belt 5 close to the position of the first motor 2.

[0026] When in use, the rock wool block is placed above the friction belt 5. The edge of the rock wool block has a higher hardness, while the surface of the rock wool block has a lower hardness. Applying a clamping force or pressure to the surface of the rock wool block will cause the rock wool block to deform. The squeezing of the clamping force will cause the rock wool block to be in an extruded state during cutting, causing the cutting surface to deflect when the rock wool strip is cut and the clamping force is removed. In the device, the electric cylinder 63 drives the clamping assembly 65 to move downward, and at the same time, the telescopic rod 64 pushes the clamping assembly 65 close to the rock wool block, so that the clamping assembly arranged opposite to the rock wool block 65 are combined, and the rock wool block is pushed to a limit position by the clamping component 65. At this time, the corner position of the rock wool block is in close contact with the clamping component 65. After the external force pushes the rock wool strip to fully fit with the clamping component 65, the first motor 2 drives the rotating roller 3 to rotate, driving the component 62 to be fixed to the friction belt 5, and the clamping component 65 and the friction belt 5 are synchronously close to the reciprocating cutting mechanism 7. The softer surface of the rock wool block is not subjected to the squeezing force, and the edge position of the rock wool block is limited, which solves the problem that the rock wool block is easy to deviate and affect the cutting accuracy during the production and cutting process of the rock wool strip.

The device is provided with a plurality of friction belts 5, and the position between each two friction belts 5 is blocked by the spacer ring 4. The position of the surface of the bending rod 623 close to the end surface is restricted by the inner concave cylinder 624. When the friction belt 5 drives the rock wool block and the bending rod 623 close to the reciprocating cutting mechanism 7, the slider 621 slides on the inner side surface of the guide rail 61, and the surface of the guide pulley 622 The surface rolls on the surface of the guide rail 61 near the opening. The sliding of the slider 621 allows the impurities deposited on the inner side of the guide rail 61 to fall through the opening, thereby avoiding blockage in the movement of the slider 621. The rock wool block and the bending rod 623 are pushed, and the softer sides, top and bottom of the rock wool block are not subjected to squeezing force. The harder corners are clamped and limited. Under the condition that the rock wool block will not be deflected, the rock wool block will not be subjected to squeezing force during cutting, so that after the clamping force is removed, the cut surface of the rock wool block is smoother.

When the saw blade 761 needs to be replaced, the rotating cover 754 is opened, the bolt 763 at the upper position is unscrewed, and the hydraulic cylinder 72 drives the limit platform 74 to move upward. Then, the saw blade 761 is separated from the fixed shell 759 at the lower position, so that the saw blade 761 can be replaced.

The limiting of the second L-shaped plate 652 makes it difficult for the rock wool block to deflect. Moreover, after the cutting of the rock wool block is completed, the sawing strip 761 penetrates into the interior of the C-shaped frame 655, and the rock wool block will not be dispersed during the whole cutting process, thereby avoiding the problem of the rock wool block being deflected when it is finally cut.

[0035] Sixth embodiment: Figure 1-Figure 9 As shown, a cross-cutting method for producing rock wool strips comprises the following steps: Step 1: clamping and limiting. Place the rock wool block above the friction belt 5. The electric cylinder 63 drives the clamping assembly 65 to move downward. At the same time, the telescopic rod 64 pushes the clamping assembly 65 close to the rock wool block, so that the clamping assemblies 65 arranged opposite to each other are combined. The rock wool block is pushed and limited by the clamping assembly 65. At this time, the corners of the rock wool block are in close contact with the clamping assembly 65, and the external force pushes the rock wool strip to fit the clamping assembly 65 completely. Step 2: synchronously drive. When the friction belt 5 drives the rock wool block and the bending rod 623 to approach the reciprocating cutting mechanism 7, the slider 621 slides on the inner side of the guide rail 61, and the surface of the guide pulley 622 rolls on the surface of the guide rail 61 near the opening. The sliding of the slider 621 allows the impurities deposited on the inner side of the guide rail 61 to fall through the opening, thereby avoiding the movement of the slider 621. The rock wool block and the bending rod 623 are pushed, and the softer side, top and bottom of the rock wool block are not subjected to the squeezing force; Step 3: reciprocating sawing. While the support assembly 75 fixedly supports the sawing assembly 76, the support assembly 75 arranged at the upper and lower positions drives the sawing assembly 76 to move reciprocatingly up and down. The friction belt 5 drives the rock wool block and the clamping assembly 65 to approach the sawing assembly 76. The rock wool block is cut into rock wool strips of uniform width by the sawing assembly 76 that moves up and down. When the rock wool block is cut by the sawing assembly 76, its corner position is effectively restricted to prevent the rock wool block from being deflected by the cutting force. Step 4, complete the cutting, the fixed table 751 supports and limits the rollers 752 and the shell 753, the surfaces of the multiple rollers 752 are in close contact with the surface of the sawing strip 761 near the end face, the rectangular frame 757 drives the sawing strip 761 to move up and down quickly, the saw teeth 762 cut the rock wool block, and the limiting of the second L-shaped plate 652 makes it difficult for the rock wool block to deflect. Moreover, after the rock wool block is cut, the sawing strip 761 penetrates into the interior of the C-shaped frame 655, and the rock wool block will not disperse during the entire cutting process.

10. A cross-cutting method for producing rock wool strips, characterized in that: The following steps are involved: Step 1: clamping and limiting. The rock wool block is placed above the friction belt (5). The electric cylinder (63) drives the clamping assembly (65) to move downward. At the same time, the telescopic rod (64) pushes the clamping assembly (65) close to the rock wool block, so that the clamping assemblies (65) arranged opposite to each other are combined. The rock wool block is pushed to limit position by the clamping assembly (65). At this time, the corners of the rock wool block are in close contact with the clamping assembly (65). External force pushes the rock wool strip to completely fit the clamping assembly (65). Step 2: synchronously drive, when the friction belt (5) drives the rock wool block and the bending rod (623) to approach the reciprocating cutting mechanism (7), the slider (621) slides on the inner side of the guide rail (61), and the surface of the guide pulley (622) rolls on the surface of the guide rail (61) near the opening position.

The support assembly (75) fixedly supports the sawing assembly (76). The support assembly (75) arranged at the upper and lower positions drives the sawing assembly (76) to move reciprocatingly up and down. The friction belt (5) drives the rock wool block and the clamping assembly (65) to approach the sawing assembly (76). The rock wool block is cut into rock wool strips of uniform width by the sawing assembly (76) that moves up and down. When the rock wool block is cut by the sawing assembly (76), the corner position of the rock wool block is effectively restricted to prevent the rock wool block from being deflected by the cutting force. Step 4: After the cutting is completed, the fixed platform (751) supports and limits the rollers (752) and the housing (753). The surfaces of the plurality of rollers (752) are in close contact with the surface of the sawing strip (761) near the end face.

The limiting effect of the second L-shaped plate (652) prevents the rock wool block from being easily deflected. Furthermore, after the cutting of the rock wool block is completed, the sawing strip (761) penetrates into the interior of the C-shaped frame (655). The rock wool block will not be dispersed during the entire cutting process.
